Abstract: 1513750 Erasing marks on magnetic-sensitive media SIMRAD AS 7 July 1975 [8 July 1974] 28582/75 Heading B6C Marks on a magnetic-sensitive medium that comprises magnetically orientatable particles rendering the medium reflective to light when the particles are orientated parallel to a surface of the medium are erased by orientating the particles using an electromagnet supported adjacent the medium by effecting relative movement between the electromagnet and the medium and simultaneously effecting repeated relative motion in a sense parallel to the surface of the medium, and perpendicular to the direction of the relative movement, and energising the electromagnet to produce a field which, in a transitional region of the medium between a region where the field is sufficiently strong to effect orientation of the particles, and a region where the field is not sufficiently strong to effect orientation, is parallel to the surface of the medium or has a component parallel to the surface larger than the component normal to the surface. This may be achieved by moving an electromagnet across the medium. In the embodiment of Fig. 1, electromagnet 7 is carried on a band 5 moved by rollers 3 and 4, current being supplied by slip contacts 8, 9. In the embodiment of Fig. 2, two electromagnets 15, 16 are mounted at respective ends of a rotatable arm.

Abstract: 1,203,336. Electric permutation locks. C. J. ALFONSI. 17 June, 1968 [20 June, l967], No. 28749/68. Heading E2A. An anti-theft device for a motor vehicle comprises a transistorised switching circuit designed so as to be responsive both to the setting of a rotary selector contact K4 and to the operation of one or more other switching devices, e.g. ignition switch K1, a switch K2 operated if casing 21 of the rotary selector contact is tampered with, or a switch K3 operated if the vehicle bonnet is opened, completion of a circuit being effected when the rotary selector contact is on any position except a neutral position, which is adjustable, should any of said other switching devices be operated, this circuit energising relays RL1, RL2, contacts r2', r2" and r2"' closed upon operation of the relays completing, respectively, a hold circuit for K4, a circuit for energising an alarm A and an electromagnetic bonnet lock BL, and a circuit by-passing distributor contacts V whereby the vehicle is disabled Each of the switches K1-K3 ap-  plies a voltage to the base of transistor T1, switch K1 applying this via a condensor C2 since a switch K'1 operated simultaneously therewith breaks the direct circuit. The resulting voltage at the emitter of transistor T1 energises transistors T3, T4 which switch in the relay RL1 for a time, determined by condensor C3, sufficient for hold contacts r2' to operate. Transistor T2 also applies a voltage to transistors T3 and T4 if a wire F is cut. An alternative normally energised electromagnetic bonnet lock BL' locks the bonnet if the main supply is cut. The switches K1, K'1, K2 and K4 are fitted on a pair of rods 27 secured either directly or, as shown, via a sleeve 34 to a cap 26 which has a plurality of circumferentially spaced projections 23 co-operating with corresponding recesses in the casing 21, the cap being liftable against the action of springs 29 to allow it to be rotated to determine a fresh neutral position for the rotary selector contact K4. The vehicle owner has then merely to adjust a disc K'4 secured to the sleeve 34 until a number corresponding to the setting is opposite a pointer 24, to enable him to start the vehicle by pressing a button 30 operating switch K1.

Abstract: 985,947. Lathes. E. C. HAHN, [trading as INDEX-WERKE KOMM. GES.]. July 26, 1962 [Aug. 3, 1961], No. 28796/62. Heading B3T. In an automatic lathe in which bar-stock 18 is fed by a gripper 34 reciprocated by a cam 46, means is provided for returning the gripper to the advanced position after it has slipped off the unusable remainder of the stock-bar, and stopping the lathe in this position with the chuck 20 open. Drive for the shaft 48 supporting the feed and chuck cams 46, 23 is from the spindle motor 56, through a shaft 60, clutch 62, and a gear train 96, 98, 100. The gear 100 is formed on one part of a clutch 104 the other part 106 of which drives the cam-shaft 48 through gears 112, 114. A spring-plunger 116 stops the driven side 106 of the clutch in the desired position, and two revolutions of the clutch 104 are required for a single revolution of the cams 46, 23 needed to advance and retract the gripper 34. At the end of a machining operation, a spring 118 engages the clutch 104 for these revolutions, under the control of a lever 86 which is operated by a cam 78 on a control shaft rotated once for each machining operation. When the returning gripper 34 slips off the waste end of stock, a spring 50 moves the gripper-slide 30 beyond its normal retracted position, the cam-follower engaging a recess 52 in the cam 46. The slide 30 operates a switch 54 controlling an electromagnet 90 which moves the cam-drum 72, aligning a further cam 79 with the lever 86 and a pair of abutments 82 with a switch 84. After the next parting-off operation, the cam 79 operates the lever 86 and allows the clutch 104 to close, the clutch remaining closed for half a revolution of the cam-shaft 48, so that the gripper 34 is advanced and the chuck 20 opened before the machine is stopped by operation of the switch 84 by one of the dogs 82. After inserting a new stock bar, the lever 86 must be operated by hand to allow the clutch 104 to close and complete a feeding cycle when the lathe is switched on. The second dog 82 operates the switch 84 to return the electromagnet and drum 72 to the first position. Specification 985,946 is referred to.

Patent GB-662314-A (GB)
Title: Improved method of producing alkali metal hydroxides
IPC: C01D1/20
Filed: 1949-11-10
Abstract: An alkali metal hydroxide solution of at least 5 per cent by weight concentration is prepared by treating a water-insoluble strongly basic anion exchange resin containing quaternary ammonium hydroxide groups with a stream of an aqueous solution of an alkali metal halide of at least 10 per cent by weight concentration and withdrawing separately the more concentrated mid-portion of the resultant alkali metal hydroxide solution.  The preferred resin is the reaction product of a chloromethylated benzene-insoluble copolymer containing a polyvinyl-aromatic compound and a monovinyl-aromatic compound with a tertiary mono-alkyl or di-alkyl N-substituted alkanolamine.  The preparation of such resins is described in Specification 679,850, [Group IV(a)].  The invention may be conducted cyclically. According to one example aqueous calcium hydroxide is passed through the bed of granular resin until the solution entering and leaving the bed has the same composition, the resin thus being converted to the quaternary ammonium hydroxide form.  After washing the resin with water, a saturated aqueous sodium chloride solution is passed through the bed, the effluent sodium hydroxide solution being collected as a series of fractions.  The first and last fractions, being of low concentration, are discarded and mid-fractions containing various concentrations of hydroxide and chloride are retained, the later of these retained fractions being saturated with sodium chloride.  In a second cycle, calcium hydroxide solution is again passed through the resin bed.  After washing the resin, the retained mid-fractions from the first cycle are fed through the bed in the order in which they were collected. The effluent sodium hydroxide solution is collected in a series of fractions and treated as in the first cycle.  This cyclic treatment is continued until a condition of balance is obtained whereupon the cycles are carried out as before except that the feeding of the retained mid-fractions is followed by the feeding of sufficient saturated sodium chloride solution to complete the reaction and the particular mid-fraction of the solution from the sodium chloride treatment in each cycle having a maximum sodium hydroxide concentration (about 16.6 per cent) is reserved for evaporation or like recovery.  Calcium hydroxide may be replaced by strontium or barium hydroxide and potassium hydroxide may also be prepared by the process.

Title: Improvements in or relating to shell fuzes
IPC: F42C15/26
Filed: 1924-08-07
Abstract: 233,378. Vickers, Ltd., and Johnson, F. G. L. Aug. 7, 1924. Projectile fuzes.-Relates to sensitive percussion fuzes in which the striker is held by a shear wire normally out of contact with a front part of a hole in the striker, the contact taking place after discharge in preparation for the impact. According to the invention, the hole c<1> in the striker C is made of such a size that the shear wire does not touch the striker either at the front, bottom, or sides of said hole, whereas, previously, the hole was a slot, the freedom from contact being only at the front. The striker is positioned by means of a slot C<2> in its side fitting a pin A<2> in the fuze body A. The striker is made hollow and of two parts as heretofore, but the firing-pin c, instead of being attached to the lower part, is made integral therewith. A cover plate G is sprung in place over the striker under a beaded edge a<x> of the fuze body. The fuze is armed by the set back of a ring F and a distancepiece F<1> when the projectile is discharged, and the subsequent opening out of centrifugal members E during flight. The striker is then moved back slightly by the air pressure until it is stopped by the shear wire, which, however, yields to the slightest blow even against a ballon fabric.

Title: Application of substance to surfaces
IPC: B03C3/013
Filed: 1967-11-14
Abstract: 1,215,647. Electrogasdynamic coating. GOURDINE SYSTEMS, Inc. 14 Nov., 1967 [15 Nov., 1966] No. 29053/68. Divided out of 1,212,539. Headings B2E and B2L. A method of coating the surface of an object, in which a gas having a coating substance entrained in it in particle form flows along a bounded flow path to an outlet, the particles are charged by ionization in the flow path and are subsequently subjected to an axial charge-repelling field, and after issuing from the outlet the charged particles set up a space charge field under the influence of which the charged particles are precipitated from the gas to form the coating on the object. In the Figure an electrogas dynamic ionizer 164 is used in a system for coating the solid objects located within an earthed metal chamber 165. The ionizer is in the form of a gun and consists of a single flow channel defined between parallel dielectric plates 166 and corona and a attractor electrodes 167, 168 respectively. It is energized from a power supply 169 which applies an ionizing potential across the electrodes 167 and 168. The ionizer includes a supporting conduit 170 having an inlet 171 for the receipt of a carrier gas in which a coating substance in particle form is entrained. The gas and the particles enter the flow channel inlet 172 where the electrical discharge field between electrodes 167, 168 results in charging taking place. Ions and charged particles move downstream under exhausted chamber 165. Creating a space charge field therein. The chamber 165 contains three solid objects to be coated, 173 is metallic, connected by a conductor 173a to the metal wall 165a of the chamber; 173b is of the dielectric material earthed by conductor 173c terminating within the object 173b; and a third object 173d is of metal or an insulating material and is not earthed. As the charged particles are emitted from the ionizer 164 into the chamber 165 the objects 173 and 173b both receive an even coating of the particles over their whole surfaces while the object 173d receives a coating only on those surfaces exposed directly to the flow of particles from the outlet of the flow channel. The method may be used to coat particles in which charges of opposite polarity to those imparted to coating particles are applied to the particles to be coated.
